Vesicles form naturally during the process of secretion(exocytosis), uptake (phagocytosis and endocytosis) and transport of materials within the cytoplasm. Alternatively, they may be prepared artificially, in which case they are called liposomes.
Answer: The reactants for Photosynthesis are the products for Cellular Respiration and the reactants of Cellular Respiration are the products of Photosynthesis.
Photosynthesis:
6CO2 + 6H2O -> C6H12O6 + 6O2
**6 Carbon Dioxide + 6 water -> Glucose + 6 Oxygen**
Cellular Respiration:
C6H12O6 + 6O2 -> 6H2O + 6CO2 + Energy
**Glucose + 6 Oxygen -> 6 Water + 6 Carbon Dioxide + Energy**
Decrease as the more frogs there are the more flies will be eaten so that means the flies will decrease.Also if the flie population gets low enough the frog population would shrink too to balance it.
